Found in its lair beneath the Taverley dungeon, Cerberus guards the River of Souls, preventing the living from entering, and the dead from escaping. Are you up to the challenge of defeating her?

She is very similar to OSRS in many ways, meaning:

You can access her lair through the Taverley dungeon, the quickest way being to run a bit north, jump across the spikes and then run further north until you come to a cave entrance

Alternatively, you can use the key master teleport to teleport very close to her lair. This scroll is dropped by Cerberus

She can only be killed while on a hellhound or Cerberus slayer task, unless there is an ongoing Cerberus event. Note that, similar to Krakens, you cannot get Cerberus or hellhounds as a slayer task unless you have a slayer streak of at least 3

At the start of the fight, a wall of flames will spawn which deals 5 damage when crossed

She can attack with all 3 styles (melee, ranged and magic)

At the start of the fight, she will use all 3 attacks in quick succession (this special attack can also hit with melee from a distance)

Once below 400 health, she can summon 3 souls that will attack you with magic, ranged or melee. They spawn in a random order but the first attack will always be from the west. Each attack will deal 30 damage and can only be blocked by a protection prayer. If you protect against an attack, 30 prayer points will be drained instead (15 prayer points if you are wielding a spectral spirit shield)

Once below 200 health, she can form 3 hot pools, one under you and two nearby. If you stand on a pool, you will take 10 - 15 damage; if you stand next to one, you will take 7 damage

She drops the smouldering stone, which can be combined with a dragon axe to create an infernal axe, which burns 1/3rd of the logs you cut, granting 100% of the firemaking XP. It can burn 5000 logs, after which it will become an infernal axe (uncharged) and you need to use a smouldering stone on it to recharge it.Combine the smouldering stone with a dragon pickaxe to create an infernal pickaxe, which smelts 1/3rd of the ore you mine, granting 100% of the smithing XP. It can smelt 5000 ores, after which it will become an infernal pickaxe (uncharged) and you need to use a smouldering on it to recharge it. If you wish to make steel, mithril, adamant or rune bars with the pickaxe, you do still need to have the appropriate amount of coal in your inventory.When uncharged, the infernal axe/pickaxe will act just like a dragon axe/pickaxe. The smouldering stone can be traded, the infernal (pick)axe cannot.

She also drops eternal, pegasian and primordial crystals, which can be combined with infinity, ranger and dragon boots respectively, requiring a runecrafting and magic level of 60 and granting 10,000 runecrafting and magic XP. The boots are similar to the ragefire, glaiven and steadfast boots we already have in the game, you can visit the OSRS wiki for the exact eternal, pegasian and primordial boots stats, which we also use.Until further notice, the ragefire, glaiven and steadfast boots will remain unchanged, so the two sets of boots will simply coexist. The eternal and pegasian boots offer slightly better stats than the ragefire and glaiven boots, while the primordial boots offer a slightly lower attack bonus than the steadfast boots (but it does have a slightly higher defense overall).

And last but not least, the hellhound puppy!

A few other things included in this update:

The dragon axe now has the proper OSRS special attack, granting +3 to your woodcutting level and using up 100% of your special attack bar. The same goes for the infernal axe and the infernal axe (uncharged)

Hellhounds now also drop the smouldering stone, as an extremely rare drop

Fixed a bug where two bosses could be in the same instance at the same time, although one of them would be unattackable (this happened outside GWD)

We're also holding a Cerberus event, which means all players can access her lair even without slayer task, her droprates are increased by 20% and her pet droprates are doubled.
